![]() ![]() This is not the same as EMC, which measures the ability of a device to operate as intended within the shared operating environment, while, at the same time, not having an effect on how additional equipment operates within the same environment. There are some clear differences, and it is important to be aware of them.ĮMI can be defined as electromagnetic energy, which impacts the functioning of an electronic device. Because of this, a lot of people tend to assume that they are two terms referring to the same thing. The terms EMC and EMI tend to be used interchangeably when referring to electronic component testing and the regulatory assessment of consumer goods. What is the difference between EMI and EMC testing? This, in turn, will ensure that there is a reasonable assurance that a device is not going to cause any damaging interference with other devices that operate within the expected operating environment.ĭue diligence and regulatory compliance require electronic devices to undergo at least one of the two types of testing mentioned above. The aim of these sort of tests is to make certain that any type of emission from the device is beneath the relevant limits that are defined for that device type. Next, we have emissions testing, which will measure the amount of electromagnetic noise that is generated by a device throughout normal operation. ![]() The aim of these tests to get a reasonable assurance that the device will perform as it is meant to when it is utilised within the expected operating environment. Immunity testing measures the reaction of the device when it is being exposed to disturbances like electromagnetic noise. Generally speaking, we can categorise this sort of test into two different categories: immunity testing and emissions testing. An EMI/EMC test is a vital step when bringing a new product to market. ![]()
